Visions of Sugar Plums by Janet Evanovich

From the publisher (source: The Internet Book List):
It's five days before Christmas and things are not looking merry for Fugitive Apprehension Agent Stephanie Plum. She hasn't got a tree. She hasn't bought any presents. The malls are jam-packed with staggering shoppers. There's not a twinkle light anywhere to be seen in her apartment-and there's a strange man in her kitchen.

Sure, this has happened to Stephanie Plum before. But this guy is different. He's mysterious, sexy-and has his own agenda. His name is Diesel, and he's on a mission. The question is, what does he want with her? Can he help her find a little old toy maker who has skipped out on his bail right before Christmas? Can he survive the Plum family holiday dinner? Can he get Stephanie a tree that doesn't look like it was grown next to a nuclear power plant? These questions and more are keeping Stephanie awake at night. Not to mention the fact that she needs to find a bunch of nasty elves, her sister Valerie has a Christmas "surprise" for the Plums, her niece Mary Alice doesn't believe in Santa anymore, and Grandma Mazur has a new stud muffin. So bring out the plastic reindeer, strap on your jingle bells, and get ready to celebrate the holidays-Jersey style.
